Maintain a race without mating

Finally scientists also solved the question, how can a small organism flourish during the past 50 million years without mating?

Bdelloid rotifer

For most animals, mating is not only a way to maintain the race but also a way to corner their enemies into the final step. Paul Sherman, a scientist at Cornell University in New York, explains: 'If creatures stop mating and' freeze 'their genomes, all of their enemies will keep up with them in evolution and soon overwhelmed them. '

This is why most unmanaged animals are afraid of distant roads to find their mates and mate.

But the Bdelloid rotifer is the only ancient asexual animal known to have survived and proliferated without sex for about 30-50 million years. During this time, they developed into more than 450 different species found throughout the Earth.

For other creatures, if spawning without mating - like a pipe - will cause their species to perish after a few hundred thousand years.

While facing the enemy are the dry parasite species, the Bdelloid rotifer . Scientists find that the longer the time to dry, the higher their chances of survival, because their enemies are less able to withstand dry conditions. After the enemies have died, Bdelloid rotifer let the wind blow them away. They will then revive immediately when exposed to freshwater environments.

So, while other creatures are stuck in the evolutionary race with their enemies, the Bdelloid rotifer escapes only by simply letting the wind swept away, leaving the enemy behind.
